🔍 Key feature: for the 2025 election, we've created our own crosswalks to handle municipality mergers and splits over time.

📈 This update allows for consistent longitudinal analysis of voting patterns, accounting for administrative boundary changes over the past 35 years.

3️⃣ Harmonized data: Two versions available:

- 2021 borders: All elections (1990-2025) mapped to 2021 municipality boundaries

- 2025 borders: All elections (1990-2025) mapped to 2025 municipality boundaries

1️⃣ Raw data: Original election results at municipality level from 1980-2025, including all parties, voter counts, and mail-in voting information.

2️⃣ Unharmonized data: Cleaned and standardized raw data with consistent variable names and formats, ready for analysis. (1980-2025)

📊 Exciting update to our German Election Database! Our federal election panels now include the 2025 German federal election.

Our paper "GERDA: The German Election Database" is out in Nature: Scientific Data!

We collected and harmonized election results for federal, state, and local elections for 1990-2021.

Updates for more recent elections, pre-1990 elections, and county elections soon!

Like this paper? Here's another that will be right up your alley.

Here, the authors merge voter files & online resumes to create a dataset of 34.5M people.

They show that Dems & Reps choose distinctive career paths and employers. This leads to a lot of partisan segregation at the workplace.

How do parties tailor their campaign ads to women? 🗳️👩

Excited to share that my paper on how parties adapt their ads is out now at @thejop.bsky.social!

The DOGE Purge: Empirical Evidence of Politically Motivated Firings And what it means for American Democracy

The DOGE Purge Isn’t About Efficiency—It’s an authoritarian tactic. I wrote a more in depth piece on the empirical evidence showing how liberal-leaning agencies are being disproportionately targeted and how this mirrors authoritarian strategies seen in Hungary and Turkey.

Yes, it bothers me so much! The experts commenting during the games are fine (although Steffen Freund is cancelled in Germany) but the halftime „expert“ duo is very incompetent…

New working paper! In this research note, @bogatyrev.bsky.social, @tabouchadi.bsky.social, @heikekluever.bsky.social, @lstoetze.bsky.social, and I present the first systematic test that causally identifies the electoral consequences of state-sponsored homophobia:

🧵Thread

About 214,000* Germans living abroad had registered to vote** in yesterday's election. Because this was a snap election with a compressed timeline, many voters didn't receive their absentee ballots in time.*** I'm one of them: mine arrived today. The day after the election.

Immer spannend zu sehen wen die AfD so auf Facebook und Instagram versucht zu erreichen 😅

🚨 Pub alert 🚨

I am incredibly excited that my first publication with the amazing Yannick Pengl, @carlmc.bsky.social, Lars-Erik Cederman and
Luc Girardin has been finally accepted
@apsrjournal.bsky.social
!
We study the consequences of increased state reach in multiethnic states.

New article now out in @thejop.bsky.social. We provide a new framework for the costs and benefits of parties' anti-elite strategies and use a novel measure based on parties' twitter messaging to analyze when they become more anti-elitist.

Maps of municipality-level election results

My fantastic co-author Julian Voss has meticulously compiled municipality-level election results for Post-WW2 Western German elections (1949-1969) from historical records. What a great resource! Read the paper, use the data: osf.io/preprints/os...

New Working Paper: Teenage boys and girls in Norway are more ideologically polarized than ever. Using data for 130,000 high-schoolers over 34 years, I find that a surge in anti-feminism among boys is driving much of the recent trend.📈
